Presentation

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

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

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

GAP

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

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