Presentation

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

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

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

GAP

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

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