Presentation

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

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

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

GAP

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

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