In a recent post to MHF I tried to form the sum![]()
+
![]()
only with the second set of subscripts equaling 7
However Latex always returned an error for all integer subscipts greater than 2
Can anyone please help

Hello, Bernhard!
In a recent post to MHF I tried to form the sum![]()
![]()
with subscripts greater than 2.
However Latex always returned an error.
Can anyone please help?
Using [tex], it will not support any expression longer than
We can produce the terms separately: .[tex]c_5[/tex] .
. . but this is very inefficient.
I recommend using [tex] tags.
[tex]c_1,c_2,c_3,c_4,\hdots[/tex] .

Hello, Bernhard!
Thanks for your help - later I will try to learn how to use [tex] tags
[tex]r_{8}[/tex] .![]()
[tex]r_2[/tex] .
[tex]r_3[/tex] .
[tex]r_4[/tex] .
[tex]r_5[/tex] .
Interesting . . . [tex] doesn't like subscripts greater than 4.
It's picky with subscripted letters too:
[tex]r_n[/tex] .
[tex]r_k[/tex] .
[tex]r_w[/tex] .
My theory is that the [tex] compiler, in its present debilitated state, can only render formulae that it has at an earlier time (before its troubles started) stored in some library of previous requests.
