Presentation

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

A minimal faithful permutation representation — 4 generators on 26 points:

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

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

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