Presentation

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

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

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

GAP

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

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