Presentation

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

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

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