In this paper we study infinite permutations generated by infinite D0L
While we have had one set of audit standards we have had to comply with many additional requirements to meet the needs of the SEC, D0L
ASTM Subcommittee D01.37, one of the newest D0l
subcommittees, was formed in 1991 as a spin-off from D01.56, which was formed in 1962.
On the other hand, certain equality languages, namely those with elementary morphisms, played a crucial role in a nice solution of the celebrated D0L
sequence equivalence problem, see [ER78].
If a d0l
language is k-power-free then it is circular.
Words constructed in this manner are often refered to as infinite D0L
