Review: [For the entire collection see Zbl 418.00002.]
The author begins by listing eighteen earlier papers of his consisting mainly of open problems in combinatorial mathematics. Then he gives a progress report on some of his favorite problems and states a few recent problems. Finally, he gives a proof of the following result. Let A(m; k) denote the least common multiple of m+1,...,m+k, and let mk be the smallest integer for which A(mk; k) > A(mk+k; k); then mk(k ––> oo as k ––> oo.
