     Re: Paging Network, Inc. and Arch Communications Group, Inc. Form S-4
         (File No. 333-94403)
         Vast Solutions, Inc. Form S-1 (File No. 333-94403-01)

Gentlemen:

     Pursuant to Rule 477(a) promulgated under the Securities Act of 1933, as
amended, Paging Network, Inc., a Delaware corporation ("PageNet"), and Arch
Communications Group, Inc., a Delaware corporation ("Arch"), hereby request that
the Securities and Exchange Commission consent to the withdrawal of the PageNet
and Arch Registration Statement on Form S-4 (File No. 333-94403), together with
all amendments, annexes and exhibits thereto and Vast Solutions, Inc., a
Delaware corporation ("Vast"), hereby requests that the Securities and Exchange
Commission consent to the withdrawal of the Vast Registration Statement on Form
S-1 (File No. 333-94403-01), together with all amendments, annexes and exhibits
thereto (collectively, the PageNet and Arch Registration Statement on Form S-4
and the Vast Registration Statement on Form S-1, together with all amendments,
annexes and exhibits thereto, are referred to as the "Registration Statements").
PageNet, Arch and Vast request withdrawal of their respective Registration
Statements because, due to the involuntary bankruptcy petition that was recently
filed against PageNet, they will now be conducting the offering and the
distribution of shares of common stock contemplated in the Registration
Statements as part of the bankruptcy proceedings and they expect that such
transactions will be exempt from registration pursuant to Section 1145 of the
Bankruptcy Code.  No shares of common stock of PageNet, Arch or Vast have been
or will be issued or sold under the Registration Statements.

     PageNet, Arch and Vast further request that, pursuant to Rule 477(c), an
order with the date of granting of the request for withdrawal be included in the
file for each Registration Statement in the following manner:  "Withdrawn upon
request of the Registrant(s), the Commission consenting thereto."
