Presentation

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

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

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

GAP

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

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