Presentation

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

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

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