Van Lier sequences
The authors study Van Lier sequences, introduced by the first two authors [J. Math. Psychol. 33, No.2, 117-130 (1989; Zbl 0693.92022)], and regular sequences. Among other results, they show that every regular sequence without gaps is a Van Lier sequence. They also show that every sub- Fibonacci sequence is a Van Lier sequence.
