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

GAP

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

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