Sorry, typo.
If k does not exactly divide 1505, the needed numbers are again
0 1 2 ... <.1505%k , in other words i.1+<.1505%k

No, the expression has to be 1+<.1505%a .
Let k be an element of a. If k exactly divides 1505
with a quotient of q, the needed numbers are
0 1 2 ... q , in other words i.1+q, in other words
i.1+<.1505%k . If k does not exactly divide 1505,
the needed numbers are again 0 1 2 ... 1+<.1505%k .

Sorry,
>. 1505 % a
Too easy to make a spelling mistake, especially a 1-pixel one.

8 6.47273 5.49254 5.23944 4.58333 3.59483
and non-integers would lead to errors in later expressions.

Hello Roger;
n =: >: 1505 % a
If this has been noted, my apologies: I'm doing Xmas catchup.

The calculation of n was off by 1, and the correction is
as
follows:>>>
a=: 215 275 335 355 420 580
n=: 1 + <.1505 % a
b=: 1505 = ((#: i.@(*/)) n) +/ .* a
n #: I. b
1 0 0 2 0 1
7 0 0 0 0 0
(n #: I. b) +/ .* a
1505 1505
