Long^{Long^{Long^{Long^{Long^{Long^{Long^{Long^LongLong} Long}Long}Long}Long}Long}Long}Long

TEXT1_{^{TEXT1_{^{TEXT1_^TEXT1}}}}

LINKS^{LINKS^{LINKS^{LINKS^{LINKS^{LINKS^{LINKS^{LINKS^LINKSLINKS} LINKS}LINKS}LINKS}LINKS}LINKS}LINKS}LINKS

LINKS_{^{LINKS_{^{LINKS_^LINKS}}}}

Its code is like this.

<center><h1> <a href="">LINKS</a>^LINKS</a></a>^LINKS</a><sup><a href="">LINKS</a>^LINKS</a><sup><a href=""><a href="">LINKS</a></a><sup>LINKS<sup><a href="">LINKS</a>^LINKS</a></sup>LINKS</a></sup> LINKS</a></sup>LINKS</a></sup>LINKS</a></sup>LINKS</a></sup>LINKS</a></sup>LINKS</a></sup>LINKS</a></h1>LINKS</a><sub><sup><a href="">LINKS</a>_^LINKS</a><sub><sup><a href="">LINKS</a></sup></sub></sup></sub></sup></sub></h1> </center>
