Presentation

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

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

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