Presentation

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

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

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

GAP

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

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