Presentation

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

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

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