Presentation

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

A minimal faithful permutation representation — 5 generators on 28 points:

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