Presentation

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

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

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

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

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