Presentation

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

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

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

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

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