The picture on the cover represents the lattice of subgroups of the Smarandache loop L 15 (8).
The lattice of subgroups of the commutative loop L 15 (8) is a non-modular lattice with 22
elements. This is a Smarandache loop which satisfies the Smarandache Lagrange criteria.
But for the Smarandache concepts one wouldn't have studied the collection of subgroups of
a loop.
