Presentation

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

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

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

GAP

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

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