right, 100^3, but I do that 10 times. Each line has 39 float values, these are not the event specifications, rather the values of 13 relations for A->B, B->C and A->C we got from the previous step (relation formulas). The goal here is to feed in the first 26 numbers to a learning algorithm and have it come up with formulas for each of the 13 relations of A->C
