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