Simple explicit expressions for named sequence transformations such as Wynn's rho algorithm (Proc. Cambridge Philos. Soc. 52 (1956) 663) and Drummond's sequence transformation (Bull. Aust. Math. Soc. 6 (1972) 69), which is used in connection with remainder estimates introduced by Levin (Int. J. Comput. Math. B 3 (1973) 371), are constructed. The elementary sequence transformations obtained in this way can be iterated leading to new nonlinear sequence transformations. Since the elementary sequence transformations, which are iterated, normally depend on n explicitly and not only implicitly via the sequence elements s(n), s(n)+1,...,s(n)+l, on which they act, there is a nonuniqueness problem which means that more than a single admissible iteration can usually be constructed. Numerical examples show that different admissible iterations of the same elementary sequence transformation may behave quite differently in convergence acceleration and summation problems.
