Computer-implemented method for operating a magnetic resonance device to acquire a magnetic resonance data set, which comprises a total number of slices, using a simultaneous multislice technique, wherein in each sequence section of a repetition sequence, which is repeated multiple times, magnetic resonance signals from a simultaneity number, which is equal to an acceleration factor, of at least two slices, which have been excited in this sequence section, are measured simultaneously, wherein, to determine an acquisition order, - a collapsed slice number, determined as the total number of slices divided by the acceleration factor, of slice groups is determined, wherein the collapsed slice number corresponds to an integer value, wherein the slices are numbered according tc their spatial arrangement in at least one stacking direction and the slice groups are defined such that the slice numbers in each group differ by the collapsed slice number, wherein the slice groups are numbered according to the lowest slice number among their slices, and - slice groups are assigned to the sequence sections according to an interleaving scheme applied to the slice groups sorted by their slice group numbers, wherein the interleaving scheme is determined by - determining multiple different time-sorted series of slice group numbers as reordering schemes for the slice groups, and - using at least one decision criterion, which describes at least an estimated slice crosstalk strength for the reordering schemes, to choose one of the reordering schemes as the interleaving scheme, characterised in that, for each reordering scheme, a series of difference numbers is calculated by - for each slice group number of the reordering scheme that is not the last slice group number of the reordering scheme, subtracting it from the following slice group number of the reordering scheme to calculate a subtraction number, wherein the subtraction number for the last slice group number is determined by subtracting the last slice group number from the collapsed slice number plus one, and - determining the difference numbers by calculating the subtraction number modulo the collapsed slice number, wherein a first of the at least one decision criterion sorts out all reordering schemes whose series of difference numbers comprises a one. - a collapsed slice number, determined as the total number of slices divided by the acceleration factor, of slice groups is determined, wherein the collapsed slice number corresponds to an integer value, wherein the slices are numbered according tc their spatial arrangement in at least one stacking direction and the slice groups are defined such that the slice numbers in each group differ by the collapsed slice number, wherein the slice groups are numbered according to the lowest slice number among their slices, and - slice groups are assigned to the sequence sections according to an interleaving scheme applied to the slice groups sorted by their slice group numbers, wherein the interleaving scheme is determined by - determining multiple different time-sorted series of slice group numbers as reordering schemes for the slice groups, and - using at least one decision criterion, which describes at least an estimated slice crosstalk strength for the reordering schemes, to choose one of the reordering schemes as the interleaving scheme, characterised in that, for each reordering scheme, a series of difference numbers is calculated by - for each slice group number of the reordering scheme that is not the last slice group number of the reordering scheme, subtracting it from the following slice group number of the reordering scheme to calculate a subtraction number, wherein the subtraction number for the last slice group number is determined by subtracting the last slice group number from the collapsed slice number plus one, and - determining the difference numbers by calculating the subtraction number modulo the collapsed slice number,
