Presentation

minimal degree	μ(G) = 26
transitive degree	μ_t(G) = 256

A minimal faithful permutation representation — 7 generators on 26 points:

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