摘要
In this note, it is proved for n <= 5 that if Q is a finite quantale with vertical bar Q vertical bar >= n, then there are at least n subquantales of Q. However, the result does not hold when vertical bar Q vertical bar >= 6. Also, an example is given of a sequence of quantales of cardinality p + 2 for p prime, each of which have exactly 5 subquantales.
