Presentation

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

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

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