Presentation

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

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

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

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

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