Line 391:

Thank you David for your guidance on refs in the lead. I've removed the ref in the last sentence of the first paragraph. I've also re-evaluated the lone reference in the 3rd paragraph. My reasons for keeping it don't fit into your general feeling about refs in the lead since what it refers to is also covered in detail in the "influence of Weierstrass and Kronecker" section. My reasons for keeping it are also not mentioned in [[WP:LEAD#Citations]]. So I'm planning to remove this ref in a few days unless someone comes up with a good reason for it. After it's removed, all the refs in the lead will be unique to the lead. --[[User:RJGray|RJGray]] ([[User talk:RJGray|talk]]) 15:19, 4 May 2016 (UTC)

== Problems with nowrap and sfrac templates ==

In the following sentence, by shrinking your window, in the first use of nowrap, you can get the subscript 1 in "''a''_''n''₁" or one of the other subscripts to wrap to the next line. In the second use of nowrap, you can get the comma in "''n_ν''," to wrap to the next line. Is there anywhere we can submit a bug report on nowrap? I switched over to " ".

:In his letter introducing the concept of countability, Cantor stated without proof that the set of positive rational numbers is countable, as are sets of the form {{nowrap|(''a''_{''n''₁, ''n''₂, …, ''n''_''ν''})}} where {{nowrap|''n''₁, ''n''₂, …, ''n_ν'',}} and ''ν'' are positive integers.

In the following sentence, nowrap is necessary because sfrac can cause a wrap after a "(" or before a ")":

:The function can be quite general—for example, ''a''_{''n''₁, ''n''₂, ''n''₃, ''n''₄, ''n''₅} = ({{sfrac|''n''₁|''n''₂}})^{{{sfrac|1|''n''₃}}} + tan({{sfrac|''n''₄|''n''₅}}).

I will be checking all uses of nowrap and sfrac in this article. --[[User:RJGray|RJGray]] ([[User talk:RJGray|talk]]) 16:20, 4 May 2016 (UTC)
