Presentation

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

A minimal faithful permutation representation — 4 generators on 28 points:

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