Presentation

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

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

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