IIS rewrite rule with HTTP status code 301 - redirect

Question

I need to write a IIS rewrite rule which matches the following condition
example.com
www.example.com
http://www.example.com
https://www.example.com
http://example.com
https://example.com
this all should redirect to https://www.example.com/somepage/
The condition is that from SEO point of view only one 301 redirection should be identified. Any pointer is appreciated
Following redirection were tried works but leads to two hops instead of one
<rule name="no path" enabled="true" patternSyntax="ECMAScript" stopProcessing="true">
<match url="(.*)" />
<conditions>
<add input="{REQUEST_URI}" pattern="^\/?$" ignoreCacom="true" />
<add input="{HTTP_HOST}" pattern="^(www.)?example.com$" ignoreCacom="true" />
</conditions>
<action type="Redirect" url="https://www.example.com/somepage" redirectType="Permanent" />
</rule>
<rule name="with path and http" enabled="true" patternSyntax="ECMAScript" stopProcessing="true">
<match url="(.*)" />
<conditions>
<add input="{PATH_INFO}" pattern="\/somepage" negate="true" ignoreCacom="true" />
<add input="{REQUEST_URI}" pattern="^\/.+$" ignoreCacom="true" />
<add input="{HTTP_HOST}" pattern="^(www.)?example.com$" ignoreCacom="true" />
<add input="{HTTPS}" pattern="^OFF$" />

Are these rules achieve your requirement?
With this rule order. http(s)://(www.)example.com/a.aspx with path will be redirected to https://www.example.com/a.aspx
https://www.example.com/a.aspx will not be redirected to avoid infinite redirection loop.
http(s)://(www.)example.com/ will be redirected to https://www.example.com/somepage.
Since it is impossible to merge everything into a rule. We need at least 3 rule to achieve this.
<rule name="https://www.example.com">
<match url="(.*)" />
<conditions logicalGrouping="MatchAll" trackAllCaptures="false">
<add input="{REQUEST_URI}" pattern="^/.+$" />
<add input="{HTTP_HOST}" pattern="www.example.com" />
<add input="{HTTPS}" pattern="^on$" />
</conditions>
<action type="None" />
</rule>
<rule name="no path" stopProcessing="true">
<match url="(.*)" />
<conditions logicalGrouping="MatchAll" trackAllCaptures="false">
<add input="{URL}" pattern="^(/)?$" />
<add input="{HTTP_HOST}" pattern="^(www\.)?example.com$" />
</conditions>
<action type="Redirect" url="https://www.example.com/somepage/" />
</rule>
<rule name="with path" stopProcessing="true">
<match url="(.*)" />
<conditions logicalGrouping="MatchAll" trackAllCaptures="false">
<add input="{REQUEST_URI}" pattern="^/.+$" />
<add input="{HTTP_HOST}" pattern="^(www\.)?example.com$" />
<add input="{REQUEST_URI}" pattern="^/somepage" negate="true" />
</conditions>
<action type="Redirect" url="https://wwww.example.com{REQUEST_URI}" />
</rule>
