In the hyperalgebra of the r-th Frobenius kernel of a universal Chevalley group over a field of characteristic p > 0, we study some subsets and the subalgebras generated by them and give some results. We are particularly interested in the case that p is 'very small' and the Dynkin diagram is not simply-laced.
