Presentation

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

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

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

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

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