Presentation

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

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

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