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