Presentation

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

A minimal faithful permutation representation — 5 generators on 28 points:

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