Presentation

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

A minimal faithful permutation representation — 3 generators on 28 points:

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