Presentation

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

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

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