Presentation

minimal degree	μ(G) = 28
transitive degree	μ_t(G) = 256

A minimal faithful permutation representation — 7 generators on 28 points:

(6,7)(10,11)(15,19)(18,20)(21,22)(23,26)(24,25)(27,28);(5,6,9,7)(8,10,12,11)(13,14,17,16)(15,18,19,20)(21,23,25,28)(22,26,24,27);(6,7)(8,12)(14,16)(18,20)(21,22,25,24)(23,26,28,27);(5,7,9,6)(8,11,12,10)(13,15,17,19)(14,18,16,20)(21,24,25,22)(23,27,28,26);(5,8,9,12)(6,10,7,11)(13,16,17,14)(15,20,19,18)(21,23)(22,27)(24,26)(25,28);(3,4);(1,2)(3,4)

GAP

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

gap> G := Group((6,7)(10,11)(15,19)(18,20)(21,22)(23,26)(24,25)(27,28), (5,6,9,7)(8,10,12,11)(13,14,17,16)(15,18,19,20)(21,23,25,28)(22,26,24,27), (6,7)(8,12)(14,16)(18,20)(21,22,25,24)(23,26,28,27), (5,7,9,6)(8,11,12,10)(13,15,17,19)(14,18,16,20)(21,24,25,22)(23,27,28,26), (5,8,9,12)(6,10,7,11)(13,16,17,14)(15,20,19,18)(21,23)(22,27)(24,26)(25,28), (3,4), (1,2)(3,4));
