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