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