Presentation

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

A minimal faithful permutation representation — 7 generators on 26 points:

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

GAP

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

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