<HTML><BODY style="word-wrap: break-word; -khtml-nbsp-mode: space; -khtml-line-break: after-white-space; ">Is there a way to insert some text, treated as an ordinary paragraph or otherwise outside the constraints of the enumerate environment, between two items?<DIV><BR class="khtml-block-placeholder"></DIV><DIV>What I have in mind is creating a numbered list using the enumeration environment, but putting either some headings or some explanatory text before groups of items, without disturbing the automatic numbering of the items. I realize that in theory this can be done by hand by ending the enumeration but then setting the appropriate counter (by hand) to the next value; however, I am thinking in terms of a subgrouping the exercises at the end of each section of a long book into (in my case) Practical Exercises, Theoretical Exercises, and Challenge Problems. But I don't want to number them separately. This is a bit like the function of \intertext, but this as I understand it works only after a \ or \\.<BR><DIV> <P style="margin: 0.0px 0.0px 0.0px 0.0px; font: 12.0px Helvetica; min-height: 14.0px"><BR></P> <P style="margin: 0.0px 0.0px 0.0px 0.0px"><FONT face="Helvetica" size="3" style="font: 12.0px Helvetica">Zbigniew Nitecki</FONT></P> <P style="margin: 0.0px 0.0px 0.0px 0.0px"><FONT face="Helvetica" size="3" style="font: 12.0px Helvetica">Department of Mathematics</FONT></P> <P style="margin: 0.0px 0.0px 0.0px 0.0px"><FONT face="Helvetica" size="3" style="font: 12.0px Helvetica">Tufts University</FONT></P> <P style="margin: 0.0px 0.0px 0.0px 0.0px"><FONT face="Helvetica" size="3" style="font: 12.0px Helvetica">Medford, MA 02155</FONT></P> <P style="margin: 0.0px 0.0px 0.0px 0.0px; font: 12.0px Helvetica; min-height: 14.0px"><BR></P> <P style="margin: 0.0px 0.0px 0.0px 0.0px"><FONT face="Helvetica" size="3" style="font: 12.0px Helvetica">telephones:</FONT></P> <P style="margin: 0.0px 0.0px 0.0px 0.0px"><FONT face="Helvetica" size="3" style="font: 12.0px Helvetica">Office<SPAN class="Apple-converted-space"><SPAN class="Apple-converted-tab"> </SPAN></SPAN>(617)627-3843</FONT></P> <P style="margin: 0.0px 0.0px 0.0px 0.0px"><FONT face="Helvetica" size="3" style="font: 12.0px Helvetica">Dept.<SPAN class="Apple-converted-space"><SPAN class="Apple-converted-tab"> </SPAN></SPAN>(617)627-3234</FONT></P> <P style="margin: 0.0px 0.0px 0.0px 0.0px"><FONT face="Helvetica" size="3" style="font: 12.0px Helvetica">Dept. fax<SPAN class="Apple-converted-space"><SPAN class="Apple-converted-tab"> </SPAN></SPAN>(617)627-3966</FONT></P> </DIV><BR></DIV></BODY></HTML>
