Presentation

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

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

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