I am working with four groups and need to add capture a unique numeric value for each group. Is there any way to access the group position?

<xsl:for-each-group select="p" group-by="group">
  <div>
    <xsl:attribute name="id">

    </xsl:attribute>
    <xsl:for-each select="current-group()">

    </xsl:for-each>
  </div>
</xsl:for-each-group>

XML:
<p>
  <text></text>
  <group>introduction</group>
</p>
<p>
  <text></text>
  <group>body</group>
</p>
<p>
  <text></text>
  <group>body</group>
</p>
<p>
  <text></text>
  <group>body</group>
</p>
<p>
  <text></text>
  <group>conclusion</group>
</p>
<p>
  <text></text>
  <group>conclusion</group>
</p>
<p>
  <text></text>
  <group>footnote</group>
</p>

Within for-each-group(), calling position() will give you values 1,2,3.... as you iterate over the groups. I would think that meets your need.
