Presentation

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

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

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