Subscripting for subscripts greater than 2
In a recent post to MHF I tried to form the sum $r_{2}$ $c_{2}$ + $r_{1}$ $c_{1}$ only with the second set of subscripts equaling 7

However Latex always returned an error for all integer subscipts greater than 2

Using [tex], it will not support any expression longer than $c_1$

We can produce the terms separately: .[tex]c_5[/tex] . $\Rightarrow\;\;c_5$
. . but this is very inefficient.

I recommend using [tex] tags.

[tex]c_1,c_2,c_3,c_4,\hdots[/tex] . $\Rightarrow\;\;c_1,c_2,c_3,c_4,\hdots$

Hello Soroban,

Thanks for your help - later I will try to learn how to use [tex] tags

$c_{5}$

[tex]r_{8}[/tex] . $r_8$

[tex]r_2[/tex] . $r_2$

[tex]r_3[/tex] . $r_3$

[tex]r_4[/tex] . $r_4$

[tex]r_5[/tex] . $r_5$

Interesting . . . [tex] doesn't like subscripts greater than 4.

It's picky with subscripted letters too:

[tex]r_n[/tex] . $r_n$

[tex]r_k[/tex] . $r_k$

[tex]r_w[/tex] . $r_w$

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.
