Presentation

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

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

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