Presentation

minimal degree	μ(G) = 28
transitive degree	μ_t(G) = 128

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

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