Presentation

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

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

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