Presentation

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

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

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