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

GAP

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

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