Presentation

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

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

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

GAP

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

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