[SVA] signal rises and stays stable check -> how to write an assertion?

In reply to ben@SystemVerilog.us:

It’s my mistake, I formulated my question badly… Actually I wanted to ask about the difference between the ##[1:3]a and *a[1:3] in assertions…

As for a[*1:3], does it means that statement ‘a’ should be repeated for 1, 2, or 3 cycles?
Will it the same as writing always(a)[*1:3]?

As for ##[1:3]a, does it mean that statement ‘a’ should be delayed for 1, 2 or 3 cycles?
