A combustor for a turbine engine comprising: a first liner defined about an axis and having a first row of circumferentially distributed first combustion air holes (114, 116, 118), a plurality of said first combustion air holes each being defined along a respective fuel injector zero pitch line (L1, L2) along which a respective fuel injector is located; and a second liner defined about said axis with a second row of circumferentially distributed second combustion air holes (120, 122), wherein the first liner is an outer liner and the second liner is an inner liner and is circumscribed by said outer liner, wherein each of said second combustion air holes (120, 122) is circumferentially offset from said fuel injector zero pitch lines (L1, L2); characterised in that: said first row of first combustion air holes (114, 116, 118) includes a three hole set in a four hole repeating pattern that includes a major outer air hole, first and second minor outer air holes that are smaller than said major outer air hole and an intermediate outer air hole that is smaller than said major outer air hole and larger than said first and second minor outer air holes; said second row of second combustion air holes (120, 122) includes a two hole set in a two hole repeating pattern, with a major inner hole and a minor inner air hole that is smaller than the major inner air hole but larger than the minor outer air holes; and the two hole repeating pattern of said second combustion air holes (120, 122) is commensurate with the number of fuel injectors. a first liner defined about an axis and having a first row of circumferentially distributed first combustion air holes (114, 116, 118), a plurality of said first combustion air holes each being defined along a respective fuel injector zero pitch line (L1, L2) along which a respective fuel injector is located; and a second liner defined about said axis with a second row of circumferentially distributed second combustion air holes (120, 122), wherein the first liner is an outer liner and the second liner is an inner liner and is circumscribed by said outer liner, wherein each of said second combustion air holes (120, 122) is circumferentially offset from said fuel injector zero pitch lines (L1, L2); characterised in that: said first row of first combustion air holes (114, 116, 118) includes a three hole set in a four hole repeating pattern that includes a major outer air hole, first and second minor outer air holes that are smaller than said major outer air hole and an intermediate outer air hole that is smaller than said major outer air hole and larger than said first and second minor outer air holes; said second row of second combustion air holes (120, 122) includes a two hole set in a two hole repeating pattern, with a major inner hole and a minor inner air hole that is smaller than the major inner air hole but larger than the minor outer air holes; and the two hole repeating pattern of said second combustion air holes (120, 122) is commensurate with the number of fuel injectors. said first row of first combustion air holes (114, 116, 118) includes a three hole set in a four hole repeating pattern that includes a major outer air hole, first and second minor outer air holes that are smaller than said major outer air hole and an intermediate outer air hole that is smaller than said major outer air hole and larger than said first and second minor outer air holes; said second row of second combustion air holes (120, 122) includes a two hole set in a two hole repeating pattern, with a major inner hole and a minor inner air hole that is smaller than the major inner air hole but larger than the minor outer air holes; and the two hole repeating pattern of said second combustion air holes (120, 122) is commensurate with the number of fuel injectors.
