Presentation

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

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

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