In mathematics, particularly in the field of homotopy theory, a **Smith set** is a specific type of set associated with a finitely generated Abelian group, particularly in the context of the Smith normal form of a matrix over the integers.

Tally in the context of voting refers to the process of counting votes to determine the outcome of an election or a decision-making process. After voters cast their ballots, the tallies are conducted to record the number of votes for each candidate, option, or proposition. The tallying process can involve different methods depending on the voting system being used. In traditional paper ballot systems, voters cast their votes on physical ballots that are then collected and counted by election officials or through automated machines.

United States military aircraft serial numbers, also known as tail numbers or designations, are unique identifiers assigned to military aircraft. These serial numbers follow specific formats and conventions, depending on the branch of service and the type of aircraft. Here are some key points about U.S. military aircraft serial numbers: 1. **Format**: The serial number is typically a combination of letters and numbers. For example, the U.S.

MMSI stands for Maritime Mobile Service Identity. It is a unique nine-digit number assigned to a ship or maritime mobile station that is used in maritime communication systems. The MMSI number is primarily used in the Automatic Identification System (AIS) and other communication systems like VHF radio to identify vessels. The MMSI number serves several purposes, including: 1. **Identification**: It helps in uniquely identifying a ship in communications and tracking systems.

The Hull Classification Symbol (HCS) is a system used by the United States Navy and other naval forces to designate the specific type and class of a ship. It consists of a combination of letters and numbers that denote various characteristics of the vessel, such as its type (e.g., aircraft carrier, destroyer, frigate), its class within that type, and sometimes additional identifying information. For instance, in the U.S.

A Pennant number is a term used in recreational mathematics and related to a specific concept in number theory. It refers to the sums of the first \( n \) triangular numbers.
