Presentation

minimal degreeμ(G) = 26
transitive degreeμt(G) = 64

A minimal faithful permutation representation — 5 generators on 26 points:

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

GAP

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

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