Presentation

minimal degreeμ(G) = 28
transitive degreeμt(G) = 256

A minimal faithful permutation representation — 7 generators on 28 points:

(7,11)(10,12)(13,14)(15,18)(16,17)(19,20);(14,17)(18,19)(21,22,25,24)(23,27,28,26);(6,9)(10,12);(3,4);(5,6,8,9)(7,12,11,10)(13,14)(15,19)(16,17)(18,20)(21,23,25,28)(22,26,24,27);(1,2)(3,4);(5,7)(6,10)(8,11)(9,12)(13,15)(14,18)(16,20)(17,19)(21,24,25,22)(23,26,28,27)

Past the SmallGroups library coverage — no SmallGroups id. Construct it from a minimal faithful permutation representation:

gap> G := Group((7,11)(10,12)(13,14)(15,18)(16,17)(19,20), (14,17)(18,19)(21,22,25,24)(23,27,28,26), (6,9)(10,12), (3,4), (5,6,8,9)(7,12,11,10)(13,14)(15,19)(16,17)(18,20)(21,23,25,28)(22,26,24,27), (1,2)(3,4), (5,7)(6,10)(8,11)(9,12)(13,15)(14,18)(16,20)(17,19)(21,24,25,22)(23,26,28,27));
