Presentation

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

A minimal faithful permutation representation — 3 generators on 28 points:

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