Presentation

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

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

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