Presentation

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

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

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