Presentation

minimal degreeμ(G) = 26
transitive degreeμt(G) = 256

A minimal faithful permutation representation — 6 generators on 26 points:

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

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

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