Some general properties of strongly asymmetric sequences generated by $m \geqq 1$ elements (m-SAS) are given. Computational experience with two algorithms—for listing of all 4-SASs of a given length n and for generating the smallest 4-SAS of length $n = 1,2, \cdots$ —supports the conjecture that there exists an infinite 4-SAS. The smallest 4-SAS of length 592 is presented.
