Presentation

minimal degree	μ(G) = 26
transitive degree	μ_t(G) = 128

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

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

GAP

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

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