Presentation

minimal degreeμ(G) = 26
transitive degreeμt(G) = 256

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

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

GAP

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

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