Presentation

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

A minimal faithful permutation representation — 6 generators on 28 points:

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

Past the SmallGroups library coverage — no SmallGroups id. Construct it from its polycyclic presentation:
