Presentation

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

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

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

GAP

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

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